Key features
- Fully open source (blockstream.com).
- Camera for QR air-gapped use (blockstream.com).
- Virtual secure element: keys are encrypted on the device and need a remote blind oracle plus your PIN to unlock (blockstream.com).
- Multisig support (blockstream.com).
Buying and setup
- Buy only from the maker's official site (blockstream.com) or an authorized seller it lists. Never use a device that arrives with a seed already written down.
- Set it up with our hardware wallet module, then pair it with Sparrow as a watch-only wallet.
